Bug in configure

[Nicholas Oxhøj]

Hi,

I tried compiling gmp-4.1.2.tar.gz on a Solaris 2.6 sun4u sparc.

The Makefile generated by configure does not work on this setup and 
causes compile errors. The problem seems to be that the code chosen for 
this system by configure (mpn/sparc32/v9/) contains "v8plus" assembler 
instructions but the compiler options generated for "cc" in the Makefile 
contains "-xarch=v8", which leads to "cc" exiting with the error message 
"cannot use v8plus instructions in a non-v8plus target binary".

./config.guess returns "ultrasparc2i-sun-solaris2.6"
./configfsf.guess returns "sparc-sun-solaris2.6"

I fixed the problem locally, by changing line 2488 of configure, such 
that the compiler option now reads "-xarch=v8plus" instead of 
"-xarch=v8". This seems to be a good fix, which should probably be 
applied to the released version of GMP:

2488c2488
<         cc_cflags="-xtarget=native -xarch=v8 -xO4"
---
>         cc_cflags="-xtarget=native -xarch=v8plus -xO4"
